I'm thinking of replacing my track/auto-x car with a sport bike. My reasoning is basically that a bike will give me far more speed for the money due to the reduced support costs of a dedicated track bike compared to a race car. I know several people on TB ride bikes of various kinds, so I'm looking for advice. PS: rig transport and other practicality issues are not a concern as I will be keeping my Tib or some simillar vehicle for day to day use. PPS: I haven't ridden a bike since I was a kid, I will be taking an MSF course and buying a cheap, low power sporter to become comfortable with riding before I get a faster track bike.
